Lubrication

The primary function of a lubricant is to lubricate the rolling and sliding contacts of a bearing to enhance its performance through the prevention of wear. This can be accomplished through various lubrication mechanisms such as hydrodynamic lubrication, electrohydrodynamic lubrication, and boundary lubrication.

In addition to wear prevention, the lubricant performs many other vital functions, including:

reduction of friction torque or power loss
improvement of cooling via heat transfer
protection against corrosion
minimize the ingress of foreign particles and contaminants

The choice of lubricant depends on the operating conditions, the environment, as well as the speed of operation of the bearing. We provide bearings dedicated to multiple applications, in various industries such as the food industry, sports or construction. For this we have a wide range of solutions adapted for all solutions.

TYPES OF LUBRICANT	APPLICATIONS	REMARKS
No Lubricant	Systems with circulating oil such as crank shafts and gearboxes. When the lubricant will be added upon mounting the bearing into the application.	Bearings treated on the surface with an anti-corrosion oil.
Grease	For lifetime lubrication. When a high degree of corrosion protection is required. When contaminations are high due to the operating environment.	Filling is done according to the percentage of the internal free volume. A high amount of grease increases protection against contamination ingress and moisture infiltration, a small percentage reduces friction torque and temperature at high speed. The following tables provide details of grease volumes, as well as a list of lubricants we typically use.
Oil	Ideal for high speed and high temperature applications	Used when the friction torque must be minimal, since oil lubrication generates very little heat.
Dry	Harsh environments at high temperatures and low rotational speeds.	When oil or grease lubrication is not feasible, there is the possibility of resorting to dry lubrication using special surface treatments on the raceway, balls or cage. Consult us to learn more about our dry lubrication technology.
